Benefits of technology
The present invention is about a spacer used in a fiber optic connector. The spacer has two portions with retention pins that engage with openings in the fiber optic ferrule. There is also a cross member that joins the two portions and has an extension. The spacer can be used with a male spacer key or a recessed portion on the cross member. The technical effect of this invention is to provide a reliable and secure connection between the fiber optic ferrule and the optical fibers, ensuring high-quality signal transmission.
Problems solved by technology
However, the spring may not always be seated properly in the spring seat (e.g., it could partially dislodge from the seat).
When the spring is not seated properly, optical connection properties (e.g., insertion loss) may suffer.
For example, when the fiber optic connector is bent due to an external force and the spring is not seated properly due to incorrect assembly of the connector, the optical alignment of the lenses in the mated ferrules may be compromised, thereby leading to an increased insertion loss.
Additionally, improper assembly of the connector by an operator may also contribute to increased insertion losses.
An operator may not assemble the connector with the correct polarity of the lensed ferrule inside the connector.
Accordingly, two sides of the connector (short and long sides) may not be configured correctly, leading to damage to the connector due to the stubbing of the mating guide pins.

Embodiment Construction
[0028]Reference will now be made in detail to the present preferred embodiment(s) of the invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.
[0029]FIG. 1 illustrates a prior art spacer 10. The spacer 10 has two portions 12,14 connected by a cross member 16. The spacer 10 has a two pins 18, 20 extending from a front face of the spacer 10. The pins 18, 20 are to engage corresponding openings in a fiber optic ferrule, not shown. The spacer 10 also has two spring retaining members 22,24 extending from a back face 26 of the spacer 10. A spring (not shown) engages the back face 26 of the spacer 10 and the two spring retaining members 22,24 center the spring on the spacer 10. However, the spring retaining members 22,24 do not always retain the spring between the two members. Additionally, the spring may snag or catch on the spring retaining members 2...

A spacer to be used with a fiber optic connector includes a two portions with spring retaining members and a cross member extending between the first and second portions. The cross member has an extension extending from the cross member between the first portion and the second portion and away from a front face thereof. The spacer may also have retention pins to engage a fiber optic ferrule.
Description
BACKGROUND OF THE INVENTION[0001]There are a number of fiber-optic connectors that use a lensed ferrule, such as the MXC® connector using the Prizm® MT ferrule. In using these fiber optic connectors, the lenses is mated fiber optic ferrules need to be aligned so that light exiting the lenses in the fiber optic ferrule in received in the lenses in the corresponding ferrule. Accordingly, alignment between the lenses in the mated ferrule is critical for having a low-insertion loss. To keep the ferrules in these connectors engaged with a corresponding ferrule and in alignment, a spring is used to bias the ferrule in at least one of the fiber optic connectors. To keep the spring in alignment with respect to the fiber optic ferrule, a spring seat is included in the fiber optic connector. For a Prizm MT ferrule, it is formed as part of the back of the ferrule.[0002]However, the spring may not always be seated properly in the spring seat (e.g., it could partially dislodge from the seat). Wh...
